Does SQL Server AlwaysOn option work with Equitrac Office and Express?
Whilst the EQCAS DB isn't actually critical to the running of the solution (if CAS>SQL connection goes down, the solution will keep working using DCE caching) there are several high availability mechanisms for SQL readily available from Microsoft. These include clustering, mirroring, and the most recent one SQL AlwaysOn / Availability Groups. It is possible to use EQ with all 3 mechanisms as the DB connection is transparent to CAS. It simply hands it off to the appropriate SQL driver, formerly ODBC, now ADO.net.
